The broad city chicks are way funnier than any chicks on any show I have ever seen
Probably because they act more like the dudes on workaholics than any other show has ever allowed a woman to behave.
There are tons and tons of funny women, but the parts are fewer and father between. Most of the good ones are essentially self-created because that's the only real way to get a fair shake that isn't fundamentally based on sexual appeal. Broad City is a part of that, it's an extension of a web series created by the two women who have connections to Amy Poehler through the UCB theater.
Joan Rivers was great.
Amy Poehler and Tina Fey are on a 10+ year run of being very consistently at the top of their craft.
Ellen is virtually a national mainstay and has been for nearly twenty years.
Wanda Sykes is great.
Sarah Silverman has been as gross as the boys for as long as anyone can remember.
Kathy Griffin is obviously entertaining.
Aubrey Plaza, Gillian Jacobs, and (especially) Alison Brie proved they were great for over half a decade on NBC.
There's a whole slew of lesser talents that are not my favorite but have their fans. There's a reason that Lisa Lampanelli is a mainstay at every roast and Janine Garafelo had steady work for 20+ years. I'm also sure that there's a reason Chelsea Handler and Whitney Cummings are popular, but I'm not in the target demo.
There's a whole group of young female comedians coming up as well. The Broad City girls are among them, but so are Shelby Fero, Amy Shumer, and Tig Notaro.
This list isn't even close to exhaustive. This is just what I can come up with sitting here at my desk. Saying women aren't funny and acting like it's just an objective fact just displays the speaker's own biases.
